I was able to boot :-) Hibernate & resuming works "well", in the same way as without this patch (as written in the previous blog-thread): Serial mouse missing after hibernation and is recoverable after a suspend-to-ram + a following `setserial -a /dev/ttyS0`.

No, both are not working. I just found the mentioned workaround for suspend to ram. But this doesn't work for resuming from hibernation because after loading the image from disk the cpu offline stuff is called.

Thanks, I'll try and put something up for your specific issue (which is odd). I still need someone who has suspend to ram working but not suspend to disk working to try this patch and see if it achieves anything at all.

is it possible for you to post some prefered or must have config settings for the kernel in conjunction with BFS? As I remember, there were always some problems with CONFIG_HZ not set to 1000. And the BOOTPARAM_HOTPLUG_CPU0 should be NO. No dynticks with HIGH_RES_TIMERS too. And you mentioned, that NUMA would be better off. Maybe the problems could be better identified than.

Hotplugcpu0 should not be enable-able but the others should only be recommendations. They shouldn't lead to failures. Nowadays I use 1000Hz with dynticks. Numa is only relevant if you're on numa hardware, and then you should enable it.
